The individuality is reality within the illusion. The illusion appears as waking or dream or mind. The individuality exists only in waking and dream. In deep sleep there is neither individuality nor duality. The dream becomes falsehood when waking takes place. Same way, the waking also becomes falsehood when one realizes the Ataman/spirit, is the true self. Therefore, one has to wake up in reality/truth to know the individuality is mere illusion.
The illusion is an object to the Self/Ataman. The illusion is mere appearance and has no permanence, whereas the witness, which is the Ataman, is formless eternal. Only when one drops all his preconceived ideas, and learns to view and judge the truth on the base of the Soul/Self. The truth starts revealing itself.
J. Krishnamurti said it best "Where there is division there must be conflict, which is disorder. This is not my law but universe law".
The division is within the waking or dream, thus the conflict is within the waking/duality. In deep sleep there is no division, therefore, there is no conflict. The one which is aware of the three states is formless soul. The nature of the Soul/Self is like deep sleep.
Thus, there is a need to know the formless witness of the three states in order to realize the individuality is falsehood. It takes a long time to grasp the witness since it is mental journey and takes time to change the base of reasoning from form to formless.
